Converting a natural gas water heater to propane is a technical process that requires careful attention to detail and adherence to safety protocols. This comprehensive guide will walk you through the step-by-step process, providing you with the necessary information to ensure a successful and safe conversion.
Preparing for the Conversion
Before you begin the conversion process, it’s essential to gather the necessary tools and materials. You’ll need the following:
- Propane conversion kit (specific to your water heater model)
- Adjustable wrench
- Screwdriver set
- Teflon tape
- Gas leak detection solution
Additionally, it’s crucial to ensure that your water heater is compatible with propane conversion. Consult the manufacturer’s instructions or contact a qualified technician to verify the feasibility of the conversion.
Changing the Gas Pressure Regulators
The first step in the conversion process is to change the gas pressure regulators. This involves adjusting the main burner regulator and the pilot burner regulator to accommodate the different gas type and pressure.
Changing the Main Burner Regulator
- Locate the gas cock knob on the water heater and turn it to the “off” position.
- Unscrew the slotted cap from the gas cock knob.
- Depress and rotate the plunger 90° to align the slot with the “LP” (Liquid Propane) markings.
- Ensure that the red disk with the white slot is at the bottom of the bore, indicating the “LP” setting.
- Replace the slotted cap.
Changing the Pilot Burner Regulator
- Locate the slotted cap on the front of the control panel.
- Unscrew the cap and align the slot with the “LP” marking.
- Push in and twist the bottom of the bore to the “LP” setting.
- Replace the slotted cap.
It’s important to note that both the main burner and pilot burner gas pressure regulators must be changed for the conversion to be successful.
Changing the Burner Orifices
The next step in the conversion process is to change the burner orifices. Burner orifices are small openings that control the amount of gas flow to the burners. Propane requires a different orifice size compared to natural gas.
- Locate the main burner and pilot burner orifices.
- Using an adjustable wrench, carefully remove the existing orifices.
- Install the new orifices provided in the propane conversion kit.
- Ensure that the orifices are tightened securely and do not over-tighten.
Modifying the Control Module (if necessary)
Depending on the water heater model, you may need to modify the control module to accommodate the propane conversion. This step is typically required for more advanced water heater models.
- Locate the control module, which is usually located behind the outer jacket door and inner door.
- Refer to the manufacturer’s instructions or the propane conversion kit for specific instructions on how to modify the control module.
- Follow the instructions carefully, ensuring that all connections are secure and properly configured.
Verifying the Conversion
After completing the conversion process, it’s essential to verify that the water heater is functioning correctly and safely.
- Turn on the gas supply and check for any gas leaks using the gas leak detection solution.
- Ignite the pilot light and observe the flame to ensure it is burning properly.
- Check the main burner operation by turning on a hot water tap and verifying that the burner ignites and maintains a stable flame.
- Measure the gas pressure at the water heater’s inlet and ensure it matches the recommended propane gas pressure specified by the manufacturer.
If any issues arise during the verification process, consult a qualified technician for further assistance.
Safety Considerations
Converting a natural gas water heater to propane is a complex task that should only be performed by a qualified professional. Improper conversion can lead to dangerous situations, such as gas leaks, fire hazards, or carbon monoxide poisoning.
It’s crucial to follow all local codes and regulations, as well as the manufacturer’s instructions, to ensure the safety of the conversion process. Additionally, some manufacturers and local codes may prohibit the conversion of water heaters from natural gas to propane or vice versa, so it’s essential to verify the feasibility of the conversion before proceeding.
Conclusion
Converting a natural gas water heater to propane requires careful attention to detail and adherence to safety protocols. By following the step-by-step guide provided in this comprehensive manual, you can successfully and safely convert your water heater to operate on propane. Remember to always consult a qualified professional if you have any doubts or concerns during the conversion process.
